The weather'stnp intended to be applied to The resiliency of the weather-strip will hold a door window or lamb member having it in installed position without the necessity for 45 45 rabbet indicated at It]. The walls of the rabbet are substantially at right angles to each other and also at right angles to the facesof the jamb. At the intersection of the faces of the rabbet ID, a longitudinal anchoring groove is cut in one face.

I 4, and into the wood of the door or jamb. This v I removed by pulling the fold l6 out of the groove in which ithas been seated.

Because of the width of the leg l8 from the.

fold IE to the bend 22 and because of the cone-- I sponding width of the leg 24, the weather-strip is provided with an ample travel yield.

A'weather-strip of this kind is free from any wrinkling or distortion such as is frequently encountered in weather-strips fastened by nails or 10 other metal jambs.

The claims appended hereto are intended to cover any modifications in the construction and arrangement of parts which may be reasonably included within their scope and the scope-of my 18 invention. For example, while I have illustrated my weather-strip as installed in connection with windows or doors of the swinging type, it will be obvious that, it could be used with sliding doors or sash.

20 I claim as my invention: a r

l. The combination of a supporting member having a rabbet and a groove formed in on wall of the rabbet, one wall of the groove forming an extension of the other wall of the rabbet, with a 25 resilient weather-strip having a seating leg in the form of a flat strip-like portion engaging a wall of the rabbet, a fold at one edge thereof received in the groove as a'seating anchor, an extension leg inclined from the fold at an acute angle of slightly less than a right angle and resiliently engaging the other wall of the rabbet, whereby the weather-strip is held in place, and a leg inclined from the outer edge of said extension leg at an acute angle thereto and toward 35 the seating leg.

2. A weather-strip adapted for-use between a closure member and a frame member, one of said members having a rabbet provided with an anchoring groove at the intersection of the walls of the rabbet, said weather-strip being provided with an anchoring leg received in said groove, a leg extending from said leg at slightly less than a right angle and engaging at its edge farthest from the first leg the wall of the rabbet in which,

groove is formed and a resilient leg inclined from said last edge over and away from the extension leg, said extension le'g having a lengthwise bend between its side edges.

4. A combination of a frame member having a rabbet at one edge and provided with a groove in one wall of the rabbet at the intersection of the rabbet walls, with a weather-strip, comprising an anchoring portion received in said groove,

a leg extending from said strip at an angle slightly less than a right angle with relation thereto the bendbetween the anchoring portion and the leg being such as to cause snug resilient contact between the free edge of the anchoring portion and the edge of the extension leg farthest therefrom and one wall of the rabbet and one wall of the groove.
